AS5048A/AS5048B Magnetic Rotary Encoder IC (14-Bit Angular Position Sensor) General Description:

The AS5048 is an easy to use 360° angle position sensor with a 14-bit high resolution output.

The IC measures the absolute position of the magnet’s rotation angle and consists of Hall sensors, analog digital converter and digital signal processing.

The absolute position information of the magnet is directly accessible over a PWM output and can be read out over a standard SPI or a high speed I²C interface. AS5048A has a SPI interface, AS5048B I²C interface. Both devices offer a PWM output.

The zero position can be programmed via SPI or I²C command.

This simplifies the assembly of the complete system because the zero position of the magnet does not need to be mechanically aligned.

The sensor tolerates misalignment, air gap variations, temperature variations and as well external magnetic fields.

This robustness and wide temperature range (-40°C up to 150°C) of the AS5048 makes the IC ideal for rotation angle sensing in harsh industrial and medical environments. Several AS5048 ICs can be connected in daisy chain for serial data read out.

An internal voltage regulator allows the AS5048 to operate at either 3.3V or 5V supplies.

The AS5048 is a magnetic Hall sensor system manufactured in a CMOS process. A lateral Hall sensor array is used to measure the magnetic field components perpendicular to the surface of the chip. The AS5048 is uses self-calibration methods to eliminate signal offset and sensitivity drifts. The integrated Hall sensors are placed around the center of the device and deliver a voltage representation of the magnetic flux Bz. Through Sigma-Delta Analog-to-Digital Converter (ADC) and Digital Signal-Processing (DSP) algorithms, the AS5048 provides accurate high-resolution absolute angular position information. This is executed by a Coordinate Rotation Digital Computer (CORDIC) which calculates the angle and the magnitude of the Hall array signals. The DSP is also used to provide digital information at the outputs that indicate movements of the magnet towards or away from the device’s surface, in the z-axis. A small diametrically magnetized (two-pole) standard magnet provides the angular position information. Depending on the system requirements different magnet diameters are possible. Additional flexibility is given by the wide range of the magnetic input range. The AS5048 can be combined with NeFeB, SmCo and alternative magnet materials e.g. hard ferrites. The AS5048 provides a 14-bit binary code representing the angular position of the magnet. The type of output is pre-programmed as SPI version A or I²C version B. Simultaneously a PWM output signal is available in 12 bit format. A simple programming of the zero position is possible over the interface. No additional programmer is needed. The AS5048 uses one time programmable (OTP) fuses for permanent programming of the user settings. The verification is possible over a simple digital readout of the OTP content.
